Cactus Soil recipe ingredients in detail.
Gravel or coarse sand: These materials provide a growing medium for the plant. Not only has that, but it also made stability to the plant. These rough materials do not absorb moisture. When growing cactus in no drainage hole pots, these large particle size materials add more value.
Perlite, Pumice: These materials absorb excess moisture. It is a crucial ingredient. Pumice cannot find easily, but it has more durability than perlite. You can read more about perlite or pumice for succulents.
Activated Charcoal: This is another water-absorbing material. Not only that, it can release moisture when the moisture reduces. Besides, charcoal prevents root rot. Therefore, this is a necessary ingredient for non-drain hole pots cactus soil mix.
